Is there a name for those glass or china eggs folks (used to) put in a nest to encourage egg-laying? I'm almost positive I've heard a term for it, but all this time spent with my head in a small box full of chickens is interfering with my memory.
in case you were wondering you can buy the ceramic/fake eggs at crackle barrel. you can get them in white or brown. they are about $1.70 each. my hens love them. my hens dont like golf balls they just push them out of the box.
